Heat is the enemy of HDD'S.
1. I really like this external enclosure:
https://www.newegg.com/p/N82E16817182247?item=9SIA0722KG3221Have a number of them. Yes, 10 screws to insert a drive (6 on the case, 4 inside for the HDD), but the internal fan is ESSENTIAL. It keeps the drive at a decent temperature even with continuous read/writes for 16 hours (see below).
2. I'm a big fan of 4TB HGST HDD's, initially standard, then NAS. Some in my HTPC have been running continuously for 2 years, basically 24/7/365. Unfortunately, Western Digital has retired the brand. Also use 2TB HGST external 2.5" HDD'S for travel. These too no longer made.
Now use WD 4TB Red's after I ran out of my stockpiled HGST's, but way too early to determine reliability.
3. For Windows, I never use an HDD until it's been provisioned:
A. LONG format, not a quick format
B. Full command line chkdsk:
chkdsk drive_letter: /x /v /r /f /b
C. Full StableBit scan (paid program)
Now, after 16+ hours of reads/writes, I'll use the HDD. My experience, a drive is either DOA, fails quickly, or runs for a long time.
4. Windows: I use 2 paid programs. They overlap some, but each has its strengths:
A. Hard Disk Sentinel: monitors my HDD temps and health. Can set alerts, with audible alarms, on overtemps (user specified); will even shut the computer down. Had an external HDD without a fan, several times, forgot to turn on the desk fan to keep it cool, audible alarm alerted me when it started to overheat. Also keeps track of health using SMART data. Author is very responsive to questions. Packs available; I have it on all my computers.
B. StableBit scanner: also monitors health, with pop-up alerts. I use this to automatically do a surface scan every 60 days (adjustable) on all my HDD's. Monitors temps during scans and will throttle scans if temps exceed your chosen temps. Author very responsive. Packs available; again on all my computers.
Both also handle SSD's appropriately; no need for surface scan.
I prefer making my own external HDD's so I know what's inside and the enclosure has a fan.
